Here's a breakdown of the formula:

* (NH₄)₂: This represents two ammonium ions (NH₄⁺).

* C₂O₄: This represents one oxalate ion (C₂O₄²⁻).

* ·H₂O: This indicates one molecule of water (H₂O) is associated with the ammonium oxalate.

Therefore, the entire formula represents one molecule of ammonium oxalate monohydrate.
